Italy is one of the major European user of cherry wood, and its cultivation has increased since the early nineties, together with several studies aimed to select and to improve the planting material for arboriculture purposes. The past establishment of clonal trials allows further investigation on the wood properties of genotypes previously selected on growth and tree architecture basis. Here, the phenotypic correlations among growth and the physical and mechanical properties of wood are investigated in two wild cherry trials. X-ray microdensitometry was also applied in order to analyse the age-age correlations for wood density. As a result, growth traits were positively and strongly correlated with each other, but not with wood properties. Growth rate did not affect wood characteristics. Density was confirmed to be the trait that best represents the main properties of wood. The absence of any relationships between wood density and growth rate was confirmed by densitometric analysis, although an increase of wood density with an increase of ring width was detected for very narrow rings (less than 3 mm wide). The average density at age 6-7 was observed to be an efficient predictor of the average density of a 19-year-old tree.
